NEW YORK OF NEW YORK, N. Y., A CORPQRATZON OF REGEPTACLE TIPPER Application filed June 23,

The present invention relates to receptacle tippers and more particularly to devices which will reverse the end position of cylindrical barrels, drums or other receptacles. An object of this invention is to provide a strong and durable construction which may be used effectively for tipping receptacles.

To this and other ends, the invention con sists of certain parts and combinations of parts all of which will be hereinafter described: the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a side view of a tipper constructed in accordance with this invention showing the tipping element in receiving position;

Fig. 2 is an end view showing the tipping element in horizontal posit-ion; and

Fig. 3 is a fragmentary View showing the tipping element in discharging position.

Referring to the illustrated embodiment of the invention, 1 indicates a supporting frame which may be of any suitable construction. This supporting frame may have bearings 2 at its top portion in which a rock shaft 3 turns. The rock shaft has the tipping memher or element at secured thereto through the medium of a saddle having depending arms 5.

The tipping element, in this instance, has a concave upper surface 6 at the opposite ends of which two abutments 7 are provided thus adapting the tipper to receive cylindrical or other round receptacles 8 between the two abutments 7 on the concave surface 6.

Supported on the frame 1 are two curved abutments 9 and 10. These abutments are arranged below the rock shaft 3 or pivotal axis of the tipping member 1, so that when the tipping member engages the abutment 9 it lies in a plane at an angle to the horizontal with its lower end below the axis or rock shaft 3, whereas, when the tipper 4 engages the other abutment 10, it lies with its opposite end below the shaft 8, as shown in 3. The abu'tments 9 and 10 may be provided with cushions 12 made of rubber or other suitable material which will absorb the shock due to the contact of the tipper with the abutments 9 and 10. It is preferred that the shaft 3 be situated nearer one end of the tip- 1927. Serial No. 200,997.

per than the other so that the latter may have a tendency to lie in the lowermost position in order that it may effectively receive a receptacle 8 from a feeding conveyor 11 as shown in Fig. 1.

With the end in view of moving a tipping element 1 so that it will engage the abutment 10 in order to reverse the end of the receptacle 8 to permit said receptacle to be moved onto the discharge conveyor 13 with its other end uppermost, a lever or arm 14; is extended from the shaft 3 and secured thereto and is provided with a foot piece or treadle 15 which when depressed swings the upper element 41 on its axis of turning. The height of this treadle, when in its uppermost position, in such that an operative, when standing on the discharge conveyor may readily reach the treadle 15 with his foot.

With the end in view of insuring the return of the tipping element to its receiving position illustrated in Fig. 1, there may be employed a means in which energy is stored when the treadle 15 is depressed to react on the tipping element to return it to its receiving position. This means, in this instance, comprises a weight 16 suspended by a frame 17 from the rock shaft on which the frame 17 turns. This frame, in this instance, has a laterally extended portion 18 with a resilient cushion or buffer 19 thereon for cooperating with the underside of the tipping element 4 to one side of the turning axis of the latter. This arm 18 provides a lost motion connection between the weight 15 and the tipping element 4, so that the tipping element may be moved independently of the weight after the weight has reached the position shown in Fig. 1.

The operation of the invention may be understood from the foregoing description but it may be summarized as follows. Assume that a container 8 on the receiving conveyor is moved from the latter onto the tipping element 4, the treadle 15 is depressed until the upper end of the tipping element 4 moves downwardly into engagement with the stop or abutment 10. After the tipping element moves a slight distance it engages the cushion 19 and then shifts the weight 16 until the latter assumes the position shown in Fig. 3. The drum or container will now be upended or tipped over so that it may be pushed onto the discharge conveyor 13 with the end thereof in engagement with the conveyor 13 opposite the end which engages theconveyor 11'. When the barrel is pushed onto the conveyor 18 and the treadle 15 released, the energy which has been stored in the weight 16 willtend to move the tipping element in the opposite direction until the weight reaches the position shown in Fig. 1 when the tipping element will proceed independently of the weight to the abutment 9 due to the fact that the receiving end of the tipping element is heavier than the discharge end. 7

WVhat we claim as our invention and desire to secure by Letters Patent is:

1. A receptacle tipping machine compri's ing a pivotally mounted tipping member having two spaced abutments for cooperating with the opposite ends of a receptacle, a treadle portion located to one side of the axis of turning of the tipping member and moving with the latter, and means for automatically moving the tipping member in the opposite direction, said means comprising a pivotally mounted weight having a lost motion connection with the tipping member, said connection being constructed to lift the weight when the tipping member isturned by the treadle and to permit the tipping memher to move independentlyoi the Weight during the final part of the movement of the tipping member toward the receiving position and the first part of the m'ovementof the tipping membertoward' discharge position.

' 2. The combination with two conveyors spaced apart, of a tipping member pivotally mount-ed between its ends above the surface of the said conveyors and over the space between the conveyors, said tipping member having abutments at opposite ends for engaging with opposite ends of a receptacle placed on the tipping member, the ends of the tipping member being adapted to swing below the upper surface of the conveyors so that a receptacle may be tilted onto one abutment from one conveyor and after the tipping member has swung to its other position it may be tilted oli vthe other abutment on to the I other conveyor.

3. The combination with two conveyors spaced apart, of a tipping member pivotally mounted between its ends above the surface of the said conveyors and over the space between the conveyors, said tipping member having abutments at opposite ends for en'- gaging with opposite ends of a receptacle placed on the tipping member, the' ends of the tipping member being adapted to swing below the upper surface of the conveyors so that a receptacle'ma'y be tilted onto one abutment from one conveyor and after the tipping member has swung to its'othe'r position the re- HABLESL; acorns c 1 ROBERT F, SUTHERLAND.
